Ultrasound — or ultrasonography — is a common, painless imaging exam. It does not expose you to radiation, unlike X-rays. Instead, it uses sound waves to create pictures of the organs and other structures inside the body. There are three types of ultrasounds:

Ultrasound is an invaluable tool to help emergency room doctors and nurses diagnose patients. In an emergency, ultrasonography can help:
In some cases, the ultrasound may take place in the emergency room. Ultrasounds typically take anywhere from 30 minutes to an hour. A technician guides a small transducer over the skin of the examination area. A water-based gel helps the transducer maintain contact with your skin. You may feel pressure as the transducer moves over your skin. Some types of exams use a probe, such as a transvaginal or transrectal ultrasound. There may be some discomfort with these exams.
There are no known risks of ultrasound. However, there is the possibility of a false-negative or false-positive result. A false-negative result is when ultrasound misses a problem that is present. A false-positive is when the ultrasound is interpreted as showing a problem that isn’t there. The accuracy and quality of an ultrasound depends on the skills of both the technician and the doctor interpreting the images.
Once the ultrasound is complete, you will return to the emergency room if you are not already there. There is no recovery necessary from the ultrasound itself. Keep in mind you may have additional imaging tests — such as X-ray, CT scan, or MRI scan — to confirm the initial results or to get more information. A radiologist will interpret the results and share them with your emergency room doctor.
